Purpose:
To report a case of multiple retinal capillary hemangioma associated with neurofibromatosis type 1 and resulting neovascularglaucoma.Case summary: A 13-year-old boy was admitted with complaint of visual disturbance and dull pain in his left eye which had beguntwo weeks prior. Lisch nodules were observed in his left iris and corneal opacity with neovascularization of the iris and anglewere detected in the same eye. Multiple retinal capillary hemangiomas with increased tortuosity and congestion of feeding retinalvessels were observed on the upper equator of the left retina; in addition, vitreous hemorrhage was observed. There were noother abnormalities except iris mammillations in the right eye. Numerous café au lait macules were observed on the patient’s entirebody. He also exhibited axillary freckling. On brain magnetic resonance imaging, T2-weighted signal intensity was increasedin the basal ganglia, left thalamus, and cerebellar white matter; however, no vessel abnormalities were observed on magneticresonance angiography. High intraocular pressure (IOP) persisted despite the use of IOP lowering agents and IOP was normalizedafter trabeculectomy with mitomycin C administration.
Conclusions
This case shows that multiple retinal capillary hemangiomas can be accompanied by neurofibromatosis type 1,which may result in neovascular glaucoma.

Pulmonary metastasis occurs frequently in patients with gestational choriocarcinoma and most of these patients achieve remission with chemotherapy alone. Thus, the indications for surgical intervention are limited, but in appropriately selected patients, resection of a chemotherapy-resistant lung lesion can be curative. We have experienced that pulmonary metastatic choriocarcinoma in a drug-resistant patient was cured by pulmonary resection. So we report this case with a brief review of literatures.

Multiple involvement of arterial fibromuscular dysplasia is unusal and such a case is quite limited in the literature. We present a case of multiple arterial fibromuscular dysplasia with aneurysm formation in a 38-year-old non-hypertensive man. Angiographic study showed multiple aneurysmal dilatations of the right renal, superior mesenteric, celiac axis, and left colic arteries. The resected right kidney demonstrated an aneurysm of the main renal artery and extensive infarction in the midportion of the renal parenchyma. The segmentally resected superior mesenteric artery disclosed a similar nature of aneurysm occluded by recent thrombi. Microscopically, all the resected arterial walls showed both intimal and medial fibroplasia together with periadventitial fibrosis resulting in marked narrowing of the lumen and subsequent thrombus formation.

A 5-year-old Labrador Retriever presented with a subcutaneous mass on the right scapular region with localized calor. On magnetic resonance imaging (MRI), a heterogeneously hypointense mass was seen on T1-weighted images (WI) and hyperintense on T2WI and fat-suppressed T2WI with marginal contrast enhancement on postcontrast T1WI and invasion into the surrounding tissue. Histopathological examination of the mass confirmed subcutaneous mast cell tumor (MCT) infiltrating to the adjacent subcutaneous fat. This is the first report to describe the MRI findings of subcutaneous MCT in veterinary medicine. This study suggests that MRI may help evaluate the extent of invasion of subcutaneous MCT.

PURPOSE: The purpose of this research was to determine the effects of a safety management program on safety accident-related knowledge, attitude and behavior of elementary school students in Korea. METHODS: This study adopted nonequivalent control group pretest-posttest design. The number of subjects was 34 in the experimental group and 31 in the control group. The safety management program was performed for approximately 50 minutes each session, once a week for 8 weeks. Data were collected from March 14th to June 23th, 2006, and analyzed by chi2 test and independent t-test with SPSS WIN 16.0. RESULTS: There were statistically significant differences in safety-related knowledge (t=3.010, p=.006) and behavior (t=18.833, p=.001) between the experimental group and the control group. The score of attitude was different between the experimental group and the control group but the difference was not statistically significant. CONCLUSION: The safety management program used in this study was appropriate for elemental school students and affected safety-related knowledge and behavior of elementary school students. Therefore safety education should be provided systematically for elementary schools over the whole country.

The authors studied the diagnostic usefulness of the Topographic analysis of EEG, using Topography ststem 700 (San-ei), in evaluation of supratentorial focal cerebral lesions of 27 patients with various etiology, comparing with visual anslysis of EEG. Focal cerebral lesions, which were proven with brain C-T, were 11 cases of cerebral infarction, 6 of intracranial hematoma, 6 of cerebral gliolysis and 4 of others. The topography system displays the spatial distribution of activity in the classic delta, theta, alpha and beta frequency and computed mapping of EEG displays equipotential maps of square of roots of power spectra over each frequency band. For visual analysis of slow waves and background activity changes, Mayo classification system of EEG abnormality was used and for visual evaluation of topographic display, above system was also applied with some modification in order to compare with the data of visual analysis of conventional EEG. The results of the study were as follows; 1. While visual analysis of conventional anlysis of EEGs showed abnormality only in 13 cases (48.1%) of 27, topographic analysis showed abnormality in 22 cases (81.5%). Topographic analysis was more sensitive than than visual analysis of the EEG and topographic analysis was thought to be more sensitive in assessment of local slow waves as well as minor changes, especially slight asymmetry, of background EEG activity. 2. Topographic analysis showed higher concor dance rate (55.6%) to the brain C-T finding in lateralization of supratentorial focal cerbral lesion than that (44.4%) of visual analysis of the conventional EEG.

A relationship between preceding acute paralytic poliomyelitis and the later development of motor neuron disease has only occasionally been suggested since it was first postulated by Charcot in 1875. The authors recently experienced a 20-year-old male who was considered to have postpoliomyelitis muscular atrophy. We report this case in view of its rarity and necessity of differential diagnosis from other neuromuscular disorders. Clinical presentation included slowly progressive muscle wasting of left thigh for 4 years, mild weakness of left arm and both thigh, intermittent fasciculation, and previous history of acute paralytic poliomyelitis. Electromyographic findings showed fibrillation potentials, positive sharp waves, fasciculations, giant motor unit potentials and reduced interference patterns. Muscle biopsy revealed scattered small angulated fibers, individual myofiber degeneration and mild inflammatory cell infiltration.

Chronic bronchiolitis is a condition associated with cigarette smoking, and later associated with pulmonary parenchymal alteration and progressive deterioration of lung function. Early respiratory bronchiolitis was produced in Sprague-Dawley rats by indirect inhalation of cigarette smoke daily in a smoke exposure chamber designed by authors for 1 month. Experimental group A (n=5) was sacrificed after having smoked 30 cigarettes, group B (n=5) after 80 cigarette, and group C (n=7) after 140 cigarettes, respectively. Examination of morphologic changes in the lungs was done on light microscope, transmission and scanning electron microscopes. Light microscopically, increase in number of goblet cells in the bronchial mucosa, brown-pigmented macrophages in the alveoli, multifocal alveolar collapse adjacent to the bronchioles, dilatation of alveolar ducts and alveolar spaces were observed. Transmission electron microscopically, irregularly shaped Clara cells, alveolar wall collapse, and focally type I epithelial cell injury were seen. Scanning electron microscopically, scattered alveolar collapse, irregular dilatation of alveolar ducts, alveolar spaces and interalveolar pores (pores of Kohn) were seen. The terminal and respiratory bronchioles showed morphological alteration of Clara cells, but no evidence of cellular bronchiolitis or bronchiolar obstruction. We conclude that sidestream smoke induces an early respiratory bronchiolitis including aggregates of brown pigmented macrophages and varying degrees of structural alteration of adjacent pulmonary parenchyma.
